Set Data Encryption Enable Flag (C7-36)
This command is meant to be used one time (only), to turn encryption ON permanently. It
elevates the security status of the device.
This is meant to be an irreversible event.
Note
: This command is supported only in non-SRED devices. In SRED devices, the reader is
always
encryption-enabled and this command is unsupported.
